SPECIFICATION forming part of Letters Patent No. 467,198, dated January 19, 1892.

Application filed August 24, 1891. fierial No. 403,582. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES R. REDEL, a citizen of the United States, residing at Rochester, in the county of Olmstead and State of Minnesota, have invented certain new and useful Improvements in Grain Separators and Cleaners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.

The invention consists in certain improvements in machines for separating and cleaning flax-seed and other grains, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a side view of a grain separating and cleaning machine provided with my improvements. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 shows certain parts in transverse section.

A designates the main frame, in which is hung a shoe B, which contains a number of screens. At each side of said shoe two horizontal rails a and a are fixed to the frame A, the extremities of said rails entering posts of the frame. Two grooved rollers c are journaled in bearings secured to the shoe B and are in position to move on the upper rail to. The lower rail a extends through apertures in the vertical pieces Z), made fast to the side of the shoe, as shown. Spiral springs d are placed on the rail ct, each of said springs bearing against one of the pieces I) and a post of the frame. A grooved roller fis journaled in bearings carried by the shoe B and is located under the rail a about midway of said rail, the latter bearing on the roller, as shown.

A reciprocatory motion is imparted to the shoe B through eccentrics G on the ends of a rotative shaft g and rods h, connected with said eccentrics and with the shoe B, the lat ter having by the action of the grooved rollers against the rails a direct forward and backward movement, the springs cl tending to assist or make steady such movement.

D indicates the uppermost screen,the same being mounted in the shoe near the top in position inclined downward from the hopper. Under the screen D is placed aplate E, which extends rearward, following the inclination of the screen D, but does not extend so far downward as said screen. Nextbelow is placed a screen D, which in position is inclined downward in a direction opposite to the direction of the screen D, and under screen D is secured a plate F, which is somewhat shorter and does not extend so far downward as the screen. Next below is placed a screen D which is inclined downward in a direction opposite to that of the screen D, and under the screen D is a plate G, which is intended to conduct refuse seed fallingthrough screen D to a channel 1', from which a spout 17?. extends out through the side of the shoe. A fourth sieve D is placednext below, and under said sieve is placed a board H, which conducts the refuse seed falling through the screen D to a channel leading to a side spout 11, extending through the side of the shoe.

J indicates a fan on a shaft having bearings in the frame, the said fan being inclosed in a housing from whicha blast-passage I extends to and connects with an upwardlyturned spout K. At the point of the connec tion of the passage I with the spout K is a discharge-spout 0, which is under the lower end of the lowest screen D The grain or seed, being turned into the hopper L, falls on the screen D at its upper end and passes through said screen to the plate E, by which it is conducted to the upper end of the screen D, the coarsest chaff or refuse passing out at the end of the screen. The grain passing through the screen D is conducted by a plate F to the upper end of screen D and passes down said screen to the upper end of screen D the refuse seed falling through screen D to the plate G, by which it is conducted to a channel that leads to a discharge side spout. The grain falling to screen D passes down the latter, any refuse seed falling through said screen being conducted by the board II to a channel leading to a discharge side spout. The cleaned grain falls from the screen D through the dischargespout 0, while any remaining chad or dust is driven by the blast from the fan J through the spout K. Four screens are shown as em ployed in connection with the shoe; but the number may be increased by adding a fifth screen if deemed expedient.
